A common type is sigma-phase, which is formed after a longer period of service in the temperature range 600 to 850 C. The amount of sigma-phase formed is related to the chemical composition of the material. Chromium rich materials are, in general, more prone to form a sigma-phase. On the other hand, elements like nickel and nitrogen hinder the formation of sigma-phase. Nitrogen is a very efficient sigma-phase blocker, which is why Sandvik 253 MA, with high chromium and low nickel, is less prone to sigma-phase formation than some of the more common materials such as ASTM 309 and ASTM 310H. Ferritic steels with more than 16% chromium are very sensitive to sigma-phase formation. Ferritic chromium steels are also prone to embrittlement in the temperature range 400 to 550 C (475 C - embrittlement). Heat treatment at 1,000 to 1,100 C dissolves most embrittling phases and returns the material to a ductile state. 36

20 Titanium and zirconium tubing In environments where not even the best stainless steels meet the corrosion resistance requirements, titanium and zirconium can be used. The manufacture of seamless titanium and zirconium heat exchanger tubes at Sandviken, Sweden, is carried out through a completely integrated process. It starts with melting of raw materials in high vacuum furnaces and ends with the finished seamless tubes. The manufacturing process is specially designed to work with non-ferrous metals like titanium and zirconium. The Sandvik group has been the world s largest independent manufacturer of seamless zirconium and titanium tubing for over 40 years, supplying to a wide range of industries including chemical, petrochemical, aerospace and nuclear. Titanium Titanium has a unique set of properties that makes it suitable for a variety of applications. It has a high environmental resistance, relying primarily on a very thin, tenacious and highly protective surface oxide film. Titanium is highly resistant to wet chlorine chemicals, practically all salt solutions, seawater, a range of acids, organic and inorganic chemicals and gases. The same oxide film provides a high resistance to erosion in high velocity process streams. The corrosion and erosion resistance makes titanium a preferred heat transfer material for shell/tube heat exchangers, since it permits the use of thin heat transfer walls and high fluid flow rates. In addition, titanium has only half the weight of steel. It is non-magnetic and is characterized by a high melting point, high strength-to-weight ratio and a low modulus of elasticity. Available Sandvik ASTM/ASME defined grades: 1, 2, 3, 4, 9, 11, 12, 16, 17, 26, 28. Other grades can be offered on request.

29 Stalatube Stalatube stainless hollow sections are used around the world in construction, building and renovation, in the food and beverage industries, offshore and marine industries, in transport and general machinery. Why choose stainless steel for structural design? Low Life Cycle Cost (LCC) Low maintenance Hygienic Corrosion resistance Strength Fire resistance Low temperature toughness Structurally aesthetic Cold formability Surface fi nish options Existing design codes 100% recyclable There are many reasons for choosing stainless hollow sections. Each application has its own priorities, plus each industry has its own standards and codes of practice. In marine environments, corrosion resistance is a priority. In architecture, the aesthetic elegance and self-healing properties are much appreciated. In the food and beverage industry, the hygienic advantages of stainless steel are vital. The combination of strength with fire resistance also offers considerable advantages over carbon steel in all kinds of structures. The examples pictured below show the amazing versatility of stainless hollow section. Needing low maintenance, and being 100% recyclable, stainless steel offers perhaps its most attractive and increasingly valued benefit: a low life cycle cost. Introduction Flat Pipe Bar steel 55

33 Introduction Value-adding services Stalatube value-adding services and know-how save you time and money in planning and on site. Cutting to length means ready to assemble. It saves waste and disposal, transport costs, time and on-site skills. Our state-of-the-art cutting equipment is fast and precise straight or angled. Flat Pipe The surface finish is an essential part of the look and functionality of a stainless steel structure. A bright surface can be produced electrolytically or mechanically. We can also handle burr-removal and washing. Laser precision cutting and perforation components are seldom just straight cut parts. To make complex structures you need angle cuttings and laser perforations. Customised high quality components from Stalatube enable fast assembly and cost savings. By using our precision cut-to-length services you get all the tube components within ± 1 mm on length and an angle tolerance of ± 1 degree. Laser cutting and perforating can produce complex ready-to-assemble shapes. Our custom packaging ensures that consignments are delivered in the best condition and ready for installation, with each package clearly identified by specification and certification. The components are ready for assembly, with no extra work or scrap. You can also get the tubes with tolerance - 0 / +20 mm in any length between 4 m and 18 m. Surface finishing We offer all conventional surface finishes such as Stalazzo brushing (standard for most dimensions), polishing (grit ), pickling and also special finishes according to your needs. Naturally, washed tubes are available if the cleanliness requirement is exceptionally high. Bar steel 59
